Fungicide resistance is the loss of efficacy of a particular type of fungicide against a target pathogen. Fungicide resistance isoften recognized when the expectations of disease control are not met when the labeled rate of a fungicide is applied.
All fungicide products have a specific mode of action (MOA), which is the way in which the fungicide affects (kills) pathogens.All fungicides are classified by MOA, and each MOA is assigned a group code called a FRAC number that will appear somewhereon the product label. FRAC stands for the Fungicide Resistance Action Committee, which is a technical group of specialists that provides fungicide resistance management guidelines to prolong the effectiveness of “at risk” fungicides and to limit crop losses dueto fungicide-resistant pathogens. See www.frac.info for the most up-to-date information on fungicide resistance and FRAC codes.
The following are some basic guidelines that should be considered in developing a fungicide program to avoid inadvertentlyselecting fungicide-resistant pathogens.
Fungicide Resistance Management Guidelines
1. Obtain an accurate disease diagnosis. This allows fungicide selection to be made correctly to minimize the chance of applyingan ineffective fungicide.
2. DO NOT apply fungicides in the absence of disease.
3. Avoid the exclusive use of a fungicide product with a single MOA or FRAC Code.
4. Rotate different MOA or FRAC Code fungicide applications if more than one application is needed within a season.
5. Use the manufacturer’s recommended rates as indicated on the label.
6. Utilize integrated disease management strategies (including host plant resistance, crop rotation, crop residue management,removal of diseased tissue on perennial crops, etc.).

CORN (FIELD) – FOLIAR DISEASESTravis Faske and Terry Spurlock
NOTE: Fungicides should not be applied prior to 100% tassel and should not be applied later than 14 days after brown silk. We do not recommend the use of fungicideson field corn in Arkansas except under extraordinary circumstances. Preventative use will likely not result in an economic return on current hybrids grown in the statein most years. In rare cases where they might be needed – such as years favorable to southern rust, late-planted corn, or corn following corn in the same field – the following foliar fungicides are registered for use in Arkansas.

Management of Corn Diseases – Fungicide Efficacy for Control of Corn Diseases (January 2018)The Corn Disease Working Group (CDWG) has developed the following information. Efficacy ratings for each fungicide listed in the table were determined by field testing the materials over multiple years and locations by members of the committee. Efficacy ratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increasesobtained from product application. Efficacy depends upon proper application timing, rate and application method to achieve optimum effectiveness of the fungicide as determined by labeledinstructions and overall level of disease in the field at the time of application. Differences in efficacy among fungicide products were determined by direct comparisons among products in field testsand are based on a single application of the labeled rate as listed in the table. The table includes systemic fungicides available that have been tested over multiple years and locations.This table is not intended to be a list of all labeled products1. Efficacy categories: NR = Not Recommended; P = Poor; F = Fair; G = Good; VG = Very Good; E = Excellent; NL = Not Labeledfor use against this disease; U = Unknown efficacy or insufficient data to rank product efficacy.NOTE: This guideline was a composite of several field trials from multiple states across the U.S. corn belt and may not always reflect fungicide efficacy observed in Arkansas.
(continued)8
1 Additional fungicides are labeled for disease on corn, including contact fungicides such as chlorothalonil. Certain fungicides may be available for diseases not listed in the table, including Gibberella and Fusarium ear rot.Application of Proline 480 SC for use on ear rots requires a FIFRA Section 2(ee) and is only approved for use in Illinois, Indiana, Iowa, Louisiana, Maryland, Michigan, Mississippi, North Dakota, Ohio, Pennsylvaniaand Virginia.
2 Harvest restrictions are listed for field corn harvested for grain. Restrictions may vary for other types of corn (sweet, seed or popcorn, etc.) and corn for other uses such as forage or fodder.A Though there is no threshold for economical use of a fungicide to control southern rust, consider yield potential, hybrid susceptibility, growth stage and weather conditions when southern rust threatens. Generally, fungicideswith a sole strobilurin mode of action are most effective when applied before southern rust is observed, and fungicides with a sole or mixed triazole mode of action are effective when applied before or after rust is found in afield. A fungicide application at tasseling or silking when southern rust has been observed on a susceptible hybrid with good yield potential may be the most beneficial at suppressing disease development; however, addi-tional application may be needed for season-long crop protection. Field corn within two weeks from physiological maturity (i.e., black layer) is very unlikely to benefit from a fungicide application.
Many products have specific use restrictions about the amount of active ingredient that can be applied within a period of time or the amount of sequential applications that can occur. Please read and follow all specific userestrictions prior to fungicide use. This information is provided only as a guide. It is the responsibility of the pesticide applicator by law to read and follow all current label directions. Reference to products in this publicationis not intended to be an endorsement to the exclusion of others that may be similar. Persons using such products assume responsibility for their use in accordance with current directions of the manufacturer. Members orparticipants in the CDWG assume no liability resulting from the use of these products.

1Certain other nematodes are considered economic problems on corn in other parts of the U.S. These include the root-knot lesion, stubby-root, ring, dagger, spiral, stunt and sting nematodes.There is no data from Arkansas to indicate the severity of these nematodes under our conditions, but at high populations a nematicide might be justified. Fields with long-term corn history thathave lower than expected yields or yields that decline over time should be tested for nematodes by submitting a soil sample to the Nematode Diagnostic Laboratory located at the SouthwestResearch and Extension Center near Hope. Contact your local county Extension agent for guidelines on when and how to collect the sample. A small fee is charged for this service.
2RESTRICTED USE PESTICIDES – These are dangerous pesticides – use caution in handling and read and follow current label directions. There has been no recent research inArkansas that demonstrates any economic return for the use of these products on corn. These products can cause crop injury if certain herbicides are applied afterwards – carefullyread pesticide interaction information on the label before applying these or any pesticides.

Target Spot(Corynespora cassiicola)
Chemical Control of Leaf Spot Diseases: Research results from other states suggest fungicides need to be applied as early as the 1st week afterbloom or by the 3rd week after bloom. Two applications appear to be the most effective. Yield responses more often occur with fields with a history ofsevere target spot, disease severity is great enough to result in defoliation levels of 30% to 50% by the 2nd or 3rd week of August, and irrigation or rainfall suggest continued increase in severity of disease. Until we know more about the disease and performance of these products in the mid-South,it is recommended to include a non-sprayed check.Headline 2.09 SC pyraclostrobin 11 6 - 12 fl oz 30Quadris 2.08 SC azoxystrobin 11 6 - 9 fl oz 45Topguard EQ 4.29 SC azoxystrobin + flutriafol 11 + 3 5 - 7 fl oz 45Priaxor 4.17 SC pyraclostrobin + fluxapyroxad 11 + 7 4 - 8 fl oz 30Elatus 45 WG azoxystrobin + benzovindiflupyr 11 + 7 6 - 7.3 fl oz 45Amistar Top 1.67 SC azoxystrobin + difenconazole 11 + 3 8.0 - 11.6 fl oz 45

COTTON – SEEDLING DISEASESTerry Spurlock
Chemical Control of Seedling Diseases of Cotton in Arkansas: 1. All cotton seed planted in Arkansas should be treated commercially. 2. Under conditions that favor seedling diseases, additional stand protection may be received from the use of in-furrow fungicides when planting treated seed (treated seed +
in-furrow combination). 3. The following products are commonly used in Arkansas cotton production to control seedling diseases.

*Botrytis gray mold has a high potential to develop resistance, and recent data suggest a high percentage of strains are resistant to several important fungicides. To help combat resistant strains from developing: (1) Limit the number of times fungicides of the same class are applied in one year. (2) Tank-mix a broad-spectrum fungicide such as captan or Thiram with Topsin-M (a benzimidazole fungicide) asTopsin-M does not have Botrytis activity due to resistance but is helpful for several early-season foliar diseases if present. (3) Resistance profiles vary from farm to farm and fungicides may have to be varied.

It is possible, however, that othernematode species such as the lesion nematode or the ring nematode may reach economic levels in some fields. If nematodes are suspected, soil samples should be collected in the fall (September-October) and sent to the Nematode Diagnostic Laboratory for analysis before the next crop is planted.

Leaf SpotsChemical Control of Leaf Spot Diseases:
1. In any given field, circular-shaped spots can be found on peanut leaves; however, these spots may not be caused by the leaf spot pathogens. Sporulation (fuzzy tufts of fungalstructures) can be seen with the aid of a hand lens on the upper leaf surfaces for ELS and lower leaf surface for LLS.
2. Fungicides on peanut are applied to prevent leaf spot disease development, which typically begins 60 days after planting, when conditions favor disease development.Fungicide programs consist of repeated applications at 14 - 21 day intervals depending on disease development and weather conditions.
3. Apply fungicides with sufficient water volume (15 to 20 GPA) to adequately cover foliage.4. Do not make consecutive applications of the same mode of action (i.e., same FRAC code number) except for those applications that contain chlorothalonil in a cropping season.
It is recommended to tank mix fungicides with a single mode of action with chlorothalonil.

Soilborne DiseasesChemical Control of Soilborne Peanut Diseases:
1. Southern blight is the most common soilborne disease of peanut in Arkansas, which is most active when weather conditions are hot and humid.2. Fungicides on peanut are applied to prevent soilborne disease development, which typically begins 60 days after planting, when conditions favor disease development.
Fungicide programs consist of repeated applications at 14 - 21 day intervals depending on disease development and weather conditions.3. Apply fungicides with sufficient water volume (15 to 20 GPA) to penetrate canopy or before rainfall. Applications at night when leaves are folded have been shown to improve
fungicide penetration into the lower canopy.4. Do not make consecutive applications of the same mode of action (i.e., FRAC group number) except for those applications that contain chlorothalonil.

1Assumes proper application and typical weather. Adverse conditions may decrease the performance of fungicides. Fungicide performance is greatly enhanced when plants are grown using proper cultural practices including maintaining continuous deep flood (especially after the very early boot stage of growth) and use of recommended N rates for the variety. Proper cultural practices greatly enhance the field resistance of rice cultivars.
2No thresholds have been developed for blast. The presence of leaf, collar and/or neck lesions in the field or nearby fields of susceptible varieties triggers consideration of a fungicide treatment.Water management and flood depth greatly influence the development of blast. Refer to the latest variety ratings available through the county Extension office for further information. All varietiesshould be inspected occasionally prior to heading as the blast fungus can adapt and attack resistant varieties.NOTE ON FUNGICIDES AND OTHER RICE DISEASES: We do not currently recommend fungicides for control of other rice diseases in Arkansas. Current fungicides used in rice are not recommended for bacterial panicle blight. Please consult the latest fungicide label for information on control of other rice diseases if deemed necessary.

Disease Fungicide Active IngredientFRACCode Rate/Acre Comments1
Fungicides to control sheath blight should be applied when effective scouting indicates more than 35% positive stops in susceptible to very susceptible varieties or more than 50%positive stops in moderately susceptible varieties between panicle differentiation and early heading. Maximum benefit from a single fungicide application will be achieved when madebefore the disease has damaged the upper 3 leaves of the canopy.

NOTE: Metalaxyl and mefenoxam have activity against Pythium and Phytophthora fungi while all others listed are more active against Rhizoctonia, Fusarium and various fungi. A combination of the two chemistries provides broadest spectrum control. If an inoculant is to be used, it should be applied after fungicide seed treatments have dried and/or right before planting.Seed treatments often have not resulted in improved stands or yields in University trials unless less-than-optimum planting conditions are prevalent (early planting, heavy clay soils, cool, wet conditions, etc.).

*Use for control of aerial blight is based on other states’ data.
Management of Soybean Diseases – Fungicide Efficacy for Control of Foliar Soybean Diseases (January 2018)The North Central Regional Committee on Soybean Diseases (NCERA-137) has developed the following information on foliar fungicide efficacy for control of major foliar soybean diseases in theUnited States. Efficacy ratings for each fungicide listed in the table were determined by field-testing the materials over multiple years and locations by the members of the committee. Efficacy ratings are based upon level of disease control achieved by product and are not necessarily reflective of yield increases obtained from product application. Efficacy depends upon proper applica-tion timing, rate and application method to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of application.Differences in efficacy among fungicide products were determined by direct comparisons among products in field tests and are based on a single application of the labeled rate as listed in thetable, unless otherwise noted. This table includes systemic fungicides available that have been tested over multiple years and locations. The table is not intended to be a list of alllabeled products1. Efficacy categories: NR = Not Recommended; P = Poor; F = Fair; G = Good; VG = Very Good; E = Excellent; NL = Not Labeled for use against this disease; U = Unknown efficacy or insufficient data to rank product efficacy.

1 Multiple fungicides are labeled for soybean rust only, powdery mildew and alternaria leaf spot,including tebuconazole (multiple products) and Laredo (myclobutanil). Contact fungicides such aschlorothalonil may also be labeled for use.
2 Cercospora leaf blight efficacy relies on accurate application timing, and standard R3 application timingsmay not provide adequate disease control. Fungicide efficacy may improve with earlier or later applica-tions. Fungicides with a solo or mixed Qol or MBC mode of action may not be effective in areas whereQol or MBC resistance has been detected in the fungal population that causes Cercospora leaf blight.
3 In areas where Qol-fungicide resistant isolates of the frogeye leaf spot pathogen are not present,Qol fungicides may be more effective than indicated in this table.
4 Harvest restrictions are listed for soybean harvested for grain. Restrictions may vary for other typesof soybean (edamame, etc.) and soybean for other uses such as forage or fodder.
5 Multiple generic products containing this mode of action may also be labeled in some states.
Many products have specific use restrictions about the amount of active ingredient that can be appliedwithin a period of time or the amount of sequential applications that can occur. Please read and followall specific use restrictions prior to fungicide use. This information is provided only as a guide. It is theresponsibility of the pesticide applicator by law to read and follow all current label directions.Reference to products in this publication is not intended to be an endorsement to the exclusion of others that may be similar. Persons using such products assume responsibility for their use in accordance with current directions of the manufacturer. Members or participants in the NCERA-137group assume no liability resulting from the use of these products.

RESTRICTED USE PESTICIDES – For sale and use only by licensed/certified applicators or persons under their direct supervision. These are dangerous pesticides – use caution in handlingand read and follow current label directions. If nematodes are suspected to be causing problems, a diagnostic soil sample should be taken to your county agent for submission to theCooperative Extension Service Nematode Diagnostic Laboratory. A small fee is required.
NOTE: The economic value of using nematicides on Arkansas soybeans is sometimes questionable. The value of soybeans in today’s market must be considered. Planting resistant varieties orusing crop rotation offers more economical control.

Management of Small Grain Diseases – Fungicide Efficacy for Control of Wheat Disease (Revised Oct. 2017)The North Central Regional Committee on Management of Small Grain Diseases (NCERA-184) has developed the following information on fungicide efficacy for control ofcertain foliar diseases of wheat for use by the grain production industry in the U.S. Efficacy ratings for each fungicide listed in the table were determined by field testing thematerials over multiple years and locations by the members of the committee. Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicideas determined by labeled instructions and overall level of disease in the field at the time of application. Differences in efficacy among fungicide products were determined bydirect comparisons among products in field tests and are based on a single application of the labeled rate as listed in the table. The table includes the most widely marketedproducts and is not intended to be a list of all labeled products.

1 Efficacy categories: NL = Not Labeled; NR = Not Recommended; P = Poor; F = Fair; G = Good; VG = Very Good; E = Excellent; --- = Insufficient data to make statement about efficacy of thisproduct.2 Product efficacy may be reduced in areas with fungal populations that are resistant to strobilurin fungicides. 3 Efficacy may be significantly reduced if solo strobilurin products are applied after stripe rust infection has occurred.4 Multiple generic products containing the same active ingredients also may be labeled in some states. Products including tebuconazole include: Embrace, Monsoon, Muscle 3.6 F, Onset, Orius
3.6 F, Tebucon 3.6 F, Tebustar 3.6 F, Tebuzol 3.6 F, Tegrol, and Toledo. Products containing propiconazole include: Bumper 41.8 EC, Fitness, Propiconazole E-AG, and PropiMax 3.6 EC.Products containing propiconazole + azoxystrobin include: Aframe Plus, Avaris 2XS.
5 Products with mixed modes of action generally combine triazole and strobilurin active ingredients. Nexicor, Priaxor and Trivapro include carboxamide active ingredients.
